Okay, so i'm really new at trying to figure things out between computers, but i've never had this issue before. I often streamed videos from my laptop to my ps3 with no problem with the router at my ex's house when I lived with him. I moved back home at the router here is driving me insane.
My dad keeps telling my it's my computer, or its the ps3's fault that keeps making the network stop, but how can that be when I can connect the my nieghbors networks just fine without this problem?
Okay, so what happened was I started streaming a video from my pc to my ps3, and the streaming was going perfectly. Then out of the blue it signs me out of the ps3 network and pops up and network error code. I went into the ps3 settings and tested the connection to the wireless router but the ps3 couldn't find the ip adress and the test failed.
I went to my laptop to try and search what was happening on here, but when i went to go to the internet there wasn't a connection to the router anymore. (so i connected to me nieghbors network instead, and went on the internet that way)

I have a dlink 615 router that was set up by telus (we have the fastest internet they offer). Both my ps3 and pc show that there is a dlink router nearby, and that it has a signal of 100% but they wont connect.
My laptop, when trying to connect to my router says, "connecting to the router is taking longer than usual." and when that screen goes it says "identifying" for a really long time untill finally it will say, "unidentified network" with limited connectivity but at 100% (the green bars are all full)...but i can't get internet or network or anything.

When i reset the router they both start to work again and connect to the internet. So after reseting I went back and started streaming one of my movies again (theres nothing wrong with the movie, i watched it a thousand times at my ex's house doing this same thing). After about 45 minutes, the same error code pops up and the internet stops working!

Which really confuses me because my dad's laptop doesn't get this issue and continues to connect to the internet through the router just fine (though he says it's really really slow then)

I don't know if it matters what types of cards we have. I believe the 80gb has a g card? My pc has an N card, and my dad's laptop has an G card. We've made sure to keep his laptop off incase it was causing problems but that hasn't improved anything.

How can i make my computer and ps3 connect to the network and be able to stream videos without this happening every time I do it? I can't even play little big planet online when I am connected to the network (its unbelievable slow) yet the router is really good!

Im sorry if i'm bad at explaining this, but i'm going to show my dad any responses so that we can figure this out.
